DRINK MIXER.

The main object of the invention is toprovide a device of the type mentioned, whereby a plurality of drinks may be is separately mixed at a time, the agitators being adapted to be operated successively, selectively or simultaneously.

Another object of the invention is to produce a drink mixer of the character mentioned, which is simple in construction, ef-

ficient in operation. and the electric driving mechanism of which is automatically set in motion when any one of its agitating elements is brought into operative position.

A further object of the invention is to provide agitating element which thoroughly mixes the liquid and at the same time aerates the drink.

With these and other objects in view, which will more fully appear as the nature of the invention is better understood, the same consists in the combination, arrangement and construction of parts hereinafter described, pointed out in the appended claims and illustrated in the accompanying drawings, it being understood that many changes may be made in the size and proportion of the several parts and details of construction within the scope of the appended claims, without departing from the spirit or sacrificing any of the advantages of the invention.

One of the many possible embodiments of the invention is illustrated in the accompanying drawings. in which Figure 1 is a top plan view of a drinkmixer constructed in accordance with the present invention; Fig. 2 is a section'taken on line 2 -2 of Fig. 1; Fig. 3 is a section taken on line 3-3 of Fig. 2; Fig. 4 is a section taken on line 4-4.- of Fig. 1, on a larger scale; Fig. 5 is a section taken on line 5-5 of Fig. 4:; Fig. 6 is a central vertical section, on a larger scale, taken through the mechanism carrying one of the agitating elements; Fig. 7 is a perspective Application filed July 8, 1922.

view of the circuit closing element of the device; Fig. 8 is an elevation, on a larger scale, of one of the agitating elements; and Fig. 9 is a section taken on line 99 of Fig. 8. I

In the drawings, the numeral 10 indicates a base plate, from which rises centrally a hollow frame member 11, carrying at its upper end a horizontally extending substantially dome-shaped frame member 12, that is also secured to a plurality of pairs of vertically extending tubular posts 13. These posts are fixed in any suitable manner to the base plate 10 and surround the frame member 11. The frame member 11 is sub stantiallyfunnel-shaped at its upper end, as shown at 14, the said funnel-shaped end, together with the dome-shaped member 12, forming a housing, in which the driving elements of the mixer are located.

Within the frame member 11 is disposed an electric motor 15, having a vertically extending driving shaft 16. To this shaft is fixedly secured in any suitable manner a friction disk 17, which is disposed within the housing above referred to. With this friction disk are adapted to be brought into engagement, in a manner hereinafter to be described, a plurality of driven disks 18. Each of these disks is carried by n agitator shaft 19, which is suitably mounted in bear ing's on a head 20. Each of these heads is carried by a pair of tubes 21, adapted to telescope into a pair of posts 18 above re ferred to. Within each tube 21 is disposed a longitudinally extending U-shaped Wire piece 22, the ends of the wire piece being securely fastened to a plug 28 at the upper end of th tube.v With this wire piece cooperates a ti -shaped wire piece 24, the ends of which are fastened to the respective post 13 adja cent its lower nd. Th two wire pieces are disposed in planes at right angles to one another and cross each other, so that their bights will be brought into engagement when the respective tube 21 is drawn out of the post 13, thereby preventing a disengagement of the elements mentioned. A helical spring 25 is located in each tube 21, the upper end of said spring being attached to the respective plug 23 and the lower end thereof to the respective standard 13. The tendency of this spring is to cause the respective head 20 to move upwards into the position shown in dotted lines in Fig. 2 of the drawings;

To each shaft 19 is detachablyfastened an agitating element 26, extending vertically downwards and including an upper cyhn- .drical portion 27, that is secured to the shaft 19, the remainder ofthe agitating element being Substantially elliptical in transverse cross-section and provided with a longitudinal groove 28 in each ofthe .opposite faces thereof. The lower-end of the agitating element is split, as shown at 29, the two split portions being bent outwards in opposite directions. The purpose of this arrangement will appear hereinafter." In each head 20 1s oscillatablymounted a vertical spindle 81, preferably-in alignment I To the upper'endofthe spindle is attached a knob with the respective driven shaft 19.

82 and to the lower end-thereofa bell 88,

that covers the respective driven disk '18.

Each bell carries a shoulder 84, co-acting with a'stop 85 on the respective head 20, to.

limit the oscillating movement of the spindle. Each bell is furthermore provided with an outwardly projecting horizontal lug 86, which is adapted to pass through a notch 87 in the frame member 12 and to cc-operate with a downwardly extending nose 88 on a I star'wheel 89. This star wheelie oscillatably mounted on a pin 40 on the frame member 12 and carries a roller 41. The roll-( er is mounted. in operative relation to an screw 44, while another wire, denoted by the numeral 48, leads to one of the terminals of the source of electric energy. The other .erminal of said source is connected by a wire 49 with the terminal screw 46. A spring 50, secured to the star wheel 89and theirame member 12, hasa tendency to shift the star and the electric circuit opened. The star rheel has as many arms and noses 88 as i here are agitating elements provided onthe vice. n "PEIfitiVG relation to each post pair .18,

head 20 until'the lug 86 hasjpassed through the respective notch 87 inthe frame member I l2. turning thenthe knob 82 in the direction of thearrow shown inFig. 8 or the drawings, the said lug, bythe intermediary v ofone of the noses 88, moves the star-wheel 89 correspondingly, thereby caus ng the roll-- er 41 to bring'the f ee endof the spring 48 into contact with the terminal screw 46,

thereby closing the electric circuit of themotor 15. .W'hen the head 20 'is' lowered, its

agitating element '26 is brought into mixing position within the receptacle 52 and the.

respectivedisk 1.8-into driving'position relative to the friction disk 17. With the trio tion elements engaged, rotation is imparted to the agitating element, and-the liquid thoroughly mixed in the'receptacle 52;

The springs 25 areobviously stronger than the-spring 50, the result being that the star wheel 89 is held in circuit closing position as long as any one of the heads 20 is in lowered position.

l A plurality of drinks may be mixed simultaneously or successively, the circuit of the electric motor being adapted to be closedby any one ofthe lugs 86 and held closed as long as any one of these lugs is'keeping'the star] wheel 89 against movement cau'sed- 'by the;

spring 50. The agitators are thus adapted to be operated successively, selectively or simultaneously, they having a common driving element, which is set into action by bringing any onset the agitating elements into operative 1positionp r ,7

thus permitting the receptacle 'to be removed fromrthebage platelO. When all of the heads are intheir elevated positions, obviously the electric circuitis interrupted and.

the motor brought to a stop.

* It isobvious that while n h s, i-

tating elements have been shown, the device may be constructed with more or less, according to the requirements, the invention residing mainly in the provision of a multiple mixer having agitating means grouped around a common driving element, in combination with a switch closing device that is adapted to be actuated by any one of the agitator carrying means.
